  • <style type="text/css">P { margin-bottom: 0.08in; }</style>

    Hi ,

    we are using windows server 2008 R2 terminal licensing server which is having 10 user CALs

    now we planned to purchase some more CALS for example additional 20 CALS per user

    Note : This is the first time we are adding the CALs in existing cals server.

    Kindly clarify my query below:

    1. what is the procedure to add the CALS with existing CALs.?

    2. while installing the new license do we need to deactivate the terminal server ?what will be the impact ?

    3. whether we need to define the users per CALs ?

  • Hi,

    Thank you for posting in Windows Server Forum.

    Based on your description, it seems that you already have RDS License server & RDS per User CAL installed on server 2008 R2. And now you want to add other RDS User CAL. For this you can follow the same procedure when you add the CAL. Also suggest you to contact MS Clearing house and explain him the whole scenario that you want to add the CAL to your existing environment and they will help you to achieve your goal. 

    Locate the Microsoft Clearinghouse Telephone Number for Your Country or Region

    More information.
    Install and issue RDS CALs or TS CALs

    Hope it helps!
